Final answer:
Without knowing the specific jurisdiction and current regulations, it is impossible to accurately determine the date on which a temporary license would be placed on inactive status for failing to complete a post-license course.
Step-by-step explanation:
If a licensee does not complete the required post-license course, the consequence is typically that their temporary license will be placed on inactive status. The exact date when this occurs would be specified in the relevant laws or regulations that govern licensing for the profession in question. Without specific information regarding the jurisdiction and pertinent regulations, it is impossible to confidently select the correct date from the options presented. It is essential to refer to the current guidelines and deadlines set by the licensing authority in the specific state or country. Such regulations are often subject to change, and up-to-date information should be consulted.
